# simple regression test for weathermap
# generate a map, dump a config, use the dumped config to generate a new map 
# if the ReadConfig and WriteConfig are working, then the two maps should be very similiar
# we use ImageMagick's compare program to check that.
#
# can extend this in the future to have 'reference' images for the suite-n.cfg files
